During night, if you have decided to go mana route, collect the stars that fall from the sky, and every 5 you can combine to make a mana crystal which boosts your mana permanently by 20. If you see any herbs that are usable for potions, make sure to take them as potions are vital in master mode. Loot any chests you can find on the surface as they will help a lot. Stay away from corruption/crimson as they are tough start-game in master mode. Try to explore the surface of your world. After the first day it won't be too hard.You can also combine your normal arrows with torches to craft flaming arrows for more damage and a chance to inflict "Fire!" debuff on enemies. These will help to pick off enemies while staying safe. If you have time, make sure to craft yourself a bow, and collect some stone to combine with wood for arrows. During the night, stay safe in your home and pick off enemies if you would like to. Building your shelter might've taken the whole day.Make sure to have 2-3 rooms during the first day and add tables and chairs, and proper walls and light sources to make sure NPCs will move in later on, and give your Guide a cozy home. Double doors unfortunately does not help against the goblins during the goblin invasion that could just break the doors.

Double doors make it so during events like blood moon when zombies could open doors, they cannot open them. Just build something that'll keep you safe from mobs. When building a shelter you don't have to get too fancy right at the beginning. When first beginning master mode you might have trouble with even the common slimes! I recommend breaking a few trees and quickly getting to build a shelter.
